Forbidden in the UK on a public highway too. Didn't stop me 'risking it' however.

I use it all the time in the winter, public roads, car parks etc... Have done so since 2015 in my xe. Never had any issues.

I actually used it today to cool down the car. Lovely.

As far as the legal aspects are concerned, at home and abroad, I think that due to my earlier points about the car being locked, immobilised etc that this is a case of the law needing to catch up with modern technology. It was probably written when you had to have the keys in the ignition to start a car, back in the bad old days.

Cheers Jarms, apart from turning the a/c and heating on do you know what else can be controlled via the remote phone app?

VEHICLE STATUS INFORMATION
Check current fuel level and range, and status of door and window position and locks. See the last parked location of your Jaguar and find your way back to it with on-foot directions.

VEHICLE MAINTENANCE ALERTS
You will be able to view maintenance issues – for example low fluid levels – and get advice on what to do next.

JOURNEY HISTORY
This opt-in feature can automatically record your journey history including your route and mileage statistics. This information can be exported by email in Excel format for expense reporting.

REMOTE CLIMATE CONTROL
Prepare your Jaguar in advance by setting temperatures to keep you and all your passengers comfortable from the moment you step inside. It is powered by remotely starting the engine.*

REMOTE BEEP AND FLASH
This feature turns on your Jaguar’s hazard lights, dipped headlights and an audible alert to help you locate it in a crowded car park.

REMOTE LOCK AND UNLOCK
Lock or unlock your doors remotely with the click of a button. Simply press the ‘lock’ button on the Vehicle Security screen of the InControl Remote Smartphone App to single lock the doors, arm the alarm, fold in the wing mirrors and close the windows. Press the ‘unlock’ button to unfold the wing mirrors, turn on the dipped headlights and cause the hazard lights to flash twice.
REMOTE ALARM RESET
You will get an alert on your smartphone if your car alarm goes off, allowing you to reset it if required.

WAKE-UP FUNCTION
To conserve battery power certain non-essential Remote features will shut down if you don’t drive your Jaguar for 4 days.

Therefore if you'd like to be able to use these services after this period of time, you can schedule a Wake-Up, which will reactivate features such as remote climate control and lock/unlock features.

The Remote Smartphone App features will be automatically reactivated the next time your Jaguar is driven.
